This league will blend the best Hall of Famers with a whole lot of top-notch Prospects. Each team will draft 4 hitters and 3 pitchers from a pool consisting of the 237 players in the Baseball Hall of Fame. The remainder of your drafted roster will be $200K players who will be waived as soon as the league starts (after which the waiver wire will be turned off). Each team will also be assigned 80 Way Above Average AAA players (60 hitters, 20 pitchers) with their real names so identifying them will be easy.

I will align the league in the morning so everyone will have most of a full day to bring up AAA players before the first game. With a 7-round draft, assigned stadiums and most of the roster 200K filler, this league should start very quickly after it fills. The draft will go on the clock 48 hours after it fills since proxies will be simple to do with such a small pool of available players. Rounds 1-2-3 will take one day each, 4-5 and 6-7 will be two rounds per day.

16-Team League (barring overwhelming interest in a 24)
7-player draft from pool of Hall of Fame players

60/20 WAA AAA (clones created by AAA matching your drafted players are allowed)

Stadium Twist: After the draft, one round will be randomly selected as the Stadium Round; your stadium will be that used in the last active season of the player you chose in that round.
No cap
50 Live Game Minimum

I want owners to have to pick and choose what they want for HOF, rather than just automatically take a bunch of sluggers. Limiting it to 4 adds some strategy to the picks, and means teams will have to use AAA extensively, which is the point.
